Patented June 17, 1930 UNITED STATES mann 'ran- J'OI-IN G. HANNA AND.ADOLF NORIN, CHIGAGO, ILLINOIS, .ASSIG'NQRS TO I-IANNA ENGINEERINGWORKS, GF CHIGAGO, ILLINOIS, CORPORATON OF ILLINOIS I' 'runnnr nIvn'rEnApplication filed. August 10,` 1925. Serial No. 49,374.v

vwith a plurality of fixed 'dies .which may be selectivelyr brought intoregistration with the movablex dies. This type of machine is usedlargely in connection with work such as the formation ofautomobileframes, each unit of which requires a number of rivetingoperations, the rivets varying in length.

It is an object oflthe present invention to provide a riveter of thischaracter having aplurality of rapidly interchangeable fixed dies. I I

It is a further object to provide such a riveter in which the fiXed diesare simple in design and construction and capable of ready removal andreplacement upon the machine rwhen necessary. vIt is an additionalobject to provide a construction in which the fixed dies may be movedfrom the cylinder side of the machine.

It is also an object to provide a structure which is simple; in designand construction and adapted forcommercial production and rapidOperation. v

Other and further objects Will appear as the description proeeeds. i

We have illustrated a prefer-red embodi- `ment of our invention in theaccompanying drawings, in which I Figure l is a side elevation of themachine; Figure 2 is a view of Figure 1 as seen from the left; v i vFigure 3 isr a view on anenlarged scale partly in section showingth'efixed die rotating and locking mechanism, and

Figurer4 is a fragmentary view showing the method of securing the fixeddie supporting members tothe turretihead.

Referring first to Figure 1, the riveter comprises the main frame 11having the turret receiving barrel 12 and the operating plunger supportl13. The operating .lever 14 is provided with extensions 15 which arejournaled upon the shaft 16. This shaft 16 is supported in the frameextension 13. The lower end of the operating lever 14 is connected bypin 17 with the piston rod 18,

which is operated by the 'piston cylinder 19. The oylinder 19 issupported upon the pin 20 carried in the extension 21 of the main frame11. The method of operating the pistonin cylinder 19 forms no part ofthe present invention and has not been disclosed in detail.

The operating lever 14 is connected by links 22 with the plunger 23Which operates through the frame portion 13. The plunger 23 carries themovable die 24.r xThe fixed dies 25 are carried by the extensions 26,which as bestshown in Figure 4, are detachably securedw to the turrethead 27 by the bolts 28. These members 26 also bear against the largeshoulder 29 on the outer end of the turret 27. I

The turret has the cylindrical extension 30, as best shown in Figure 3,,which eXtends through the barrel 12 of the main frame. The rod 31extends outwardly from the end of the turret member and the collar 32 isrotatably fitted upon the rod 31 and retained in place by the nut 33.The control handle 34 is pivotally supported `rupon the collar 32 andcarries the plunger 35 Which is pressed outwardly by spring 36 againstthe lug 37'whichv extends fromV the collar 32. The handle 34 is providedwith the lug 38 which is adapted to engage in the notch 39 in the flange40. This flange 40 is secured. to the barrel 12 by bolts 41, as bestshown in Figure 3. The handle 34 is also provided With the deeper lug 42which is adapted to engage any oneofthe notches 43 fornied in the end ofthe turret member.

In the Operation of-the riveter, the movable plunger 23 and movable die24 are reciprocated by admitting a compressedfiuid selectively upon theopposite sides of the piston carried in cylinder 19. This serves to rockthe operating lever about the shaft 16 and perform the rivetingOperation. The turret head is shown as provided [with four members 27carrying fixed dies 25 of different heights which are thus adapted tocooperate with the movable die to drive rivets of different length.

The turret is looked with any desired fiXed die in registration with themovable die Vby the engagement of the lugs 38 and 42 with the notch 39and a registering notch 43. To move the next ixed die into registrationwith the movable die, the handle 34 is swung outwardly against the lug37, the spring 36 being compressed and is then swung in thecounter-clockwise direction to the position shown in Figure 2. Duringthis movement, the lug 42 will be riding on the end of theturret memberand when'it reaches the next notch 43 will be dropped down into thatnotch by the power of the spring 36. The lug 38 will now rlde on theflange 40. The handle is next ro-r tated in the clockwise directionuntil the ment of our invention in the accompanying drawings by Way ofillustration only, and We contemplate such changes and modifications ascome within the spirit and scope of the accompanying claims.
